Gravidity and parity
open-in-new
<p>In <a href="/facts/Biology/1M1ee3pB">biology</a> and <a href="/facts/Medicine/2fnp90Je">medicine</a>, gravidity and parity are the number of times a female has been <a href="/facts/Pregnant/vEKYGpep">pregnant</a> (gravidity) and carried the pregnancies to a viable gestational age (parity). These two terms are usually coupled, sometimes with additional terms, to indicate more details of the female's obstetric history. When using these terms: </p> <ul><li>Gravida indicates the number of times a female is or has been pregnant, regardless of the pregnancy outcome. A current pregnancy, if any, is included in this count. A multiple pregnancy (e.g., twins, triplets, etc.) is counted as 1.</li> <li>Parity, or "para", indicates the number of births (including live births and stillbirths) where pregnancies reached <a href="/facts/Fetal_viability/HNFrF9lu">viable gestational age</a>. A multiple pregnancy (e.g., twins, triplets, etc.) carried to viable gestational age is still counted as 1.</li> <li><a href="/facts/Abortus/ro0RjIBT">Abortus</a> is the number of pregnancies that were lost prior to viable gestational age for any reason, including induced abortions or <a href="/facts/Miscarriage/sFq0vdnU">miscarriages</a> but not stillbirths. The abortus term is sometimes dropped when no pregnancies have been lost.</li></ul>
